Demonstrations are commonly used to speed up the learning process of Deep Reinforcement Learning algorithms.

Imitation Learning

Leveraging Sequentiality in Reinforcement Learning from a Single Demonstration

1 code implementation9 Nov 2022 Alexandre Chenu, Olivier Serris, Olivier Sigaud, Nicolas Perrin-Gilbert

This sequential goal-reaching approach raises a problem of compatibility between successive goals: we need to ensure that the state resulting from reaching a goal is compatible with the achievement of the following goals.

Divide & Conquer Imitation Learning

1 code implementation15 Apr 2022 Alexandre Chenu, Nicolas Perrin-Gilbert, Olivier Sigaud

In such context, Imitation Learning (IL) can be a powerful approach to bootstrap the learning process.

Selection-Expansion: A Unifying Framework for Motion-Planning and Diversity Search Algorithms

no code implementations10 Apr 2021 Alexandre Chenu, Nicolas Perrin-Gilbert, Stéphane Doncieux, Olivier Sigaud

In particular, we show empirically that, if the mapping is smooth enough, i. e. if two close policies in the parameter space lead to similar outcomes, then diversity algorithms tend to inherit exploration properties of MP algorithms.
